I can't tell you how far from helping me those two links were. The 2nd one was something to do with TV service manuals wasn't it? Either that or Chinese poetry.
I'm not saying they wouldn't have helped somebody - just not me.
No I'm not using Veritas Netbackup.

Hey, no problem!

Do you know what these .ci files are about? I gather they're something to do with indexing but thats as far as I got.

I give up

By default, the Catalog.wci directory is created on your Web server during the installation of Microsoft Index Server. You can usually find the catalog directory under the InetPub directory on the drive where you installed IIS.

2) The more people use the hard drive the higher the index becomes
3) You can try turning off Indexing on your hard drive to boost the performance.
4) Shouldnt worry unless your performance is degrading

Thanks for that.

I also have a catalog.wci in that directory but that is small. I assume this one in System Volume Information is not related to IIS. Is it related to the Windows Indexing Service? As there is only around 130GB total on this server and only 90GB of that is on the D drive I kind of thought an index of 21GB was more than necessary so wondered if there was something nasty going on.

Is this a typical situation for a DC/File server on a 20 user network?

this .ci file is an indexfile of the content indexer coming with IIS or SQL.
disable all content indexing to prevent this file from creation/growing.

You can always try emptying the index via WMI in the Control Panel. I am sure that the max size is configurable. As its set to unlimited by default
